About

I am a PhD student at the University of Chicago and the Field Museum of Natural History studying birds. My interests include biogeography, evolutionary biology and conservation with a tropical emphasis.

A male Loxigilla violacea ruficollis in the company of at least one female in wet limestone forest. The birds were foraging at close range with the male aggressively singing. Recording made with an iPhone.

The bird was singing along a road cut through partially flooded discidious woodland adjacent to a lake. Seen extremely well from as close as eleven meters as it sang approximately four meters above the ground. Recorded with an iPhone 4S.

Lone male was calling in the top of a seeding elm tree. The bird was flying between a few perches and voraciously eating the elm seeds, and calling constantly while perched. No other crossbills were seen in the area.

Extremely quiet because it was recorded with my iPhone. Singing from the top of a tree near the parking lot at the visitor center. Appeared to be keeping as high as possible, and moving about sporadically.

The bird was first heard and then seen singing and sporadically foraging approximately three meters above the ground in closed canopy riparian forest. The forest is a fragment within agricultural land and adjacent to large expanses of montane forest.

This recording is edited for time, but has not been altered in any other way.

Flock was foraging approximately two meters above the ground at the edge of Afromontane forest along a well-maintained trail. The birds were interacting and were frequently giving these contact calls. They were seen extremely well. Identified to ssp. by range and visuals.

Identified using Chappuis tapes; matches introductory calls to song, but repeated over and over. Calling in secondary forest not far from road. Direction of calling bird was towards primary forest at higher elevation.

Bird responded to playback of it's call and flew by briefly. Was confirmed by comparing song to recordings. On territory along small tributary in the wilderness area. Call is completely unaltered; made with iPhone.

Singing in mature secondary forest surrounded by a matrix of agricultural land. Seen earlier in the morning but not during recording session. 0:38 contains some microphone noise as I tried to readjust my position.

Two birds doing a long series of calls from a large tree in a patch of mature secondary within a matrix of agricultural land. The birds were calling back to another pair of Corythaeola cristata (audible in the background).

Two birds doing a long series of calls from a large tree in a patch of mature secondary within a matrix of agricultural land. Very last call in the recording was given by the bird as it was flying away. The birds were calling back to another pair of Corythaeola cristata (audible in the background).

Distant recording of a Pel's Fishing-Owl at the edge of a Palm Swamp in lowland rainforest. The bird was calling sporadically throughout both of our days at this location. Notes are most audible in this recording at 0:10 and 0:21.

Undoubtedly missing the ID's of some species, but the background species list is pretty representative of the birds present at this location. This recording was made from near the highway in secondary agricultural forest; many of these birds are singing in thicker secondary and primary forest on the slopes above my location. The background "noise" is a mix of greenbuls, predominately Eurillas virens and Arizelocichla tephrolaema. A complete list of birds and species from this location and date is available here: http://ebird.org/ebird/view/checklist?subID=S20984700.

Bird giving a scold call from dense undergrowth in secondary forest adjacent to agricultural land. Bird was seen previous to this recording, and either this bird or one from an adjacent territory was later caught and banded less than 100 meters away.

The bird was singing from the top of a tree along the edge of mature secondary and active agricultural areas. The recording was not modified in any way, and the bird was singing naturally. Views were poor, but identifiable, and several other active Arizelocichla tephrolaema were seen in the immediate vicinity before and after the recording.
